Weight on?

Question

HOW DO I PUT ON WEIGHT??
This question may get moaned at for being 'ungrateful' for my figure but that's certainly not the case, I'm 16 and a size 6 with a bra size of 28A. I eat lots and have a balanced diet. 
Please no rude comments,I feel uncomfortable being this slim and I'd just like to put a small amount of weight on? I'd really appreciate any help!

Answer

A size 6 is an average size!

Carbs. Sugar. Not exersizing. Um fast food. Idk man.

Answer

Eat heaps and heaps of protein and carbs (track them if you can and try to crack 10000kj daily for steady weight gain) and lift weights :)
